In a sperm cell what important structures are found inside the nuclaeus?

Answer 1

In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, meaning kernel), also sometimes referred to as the "control center", is a membrane-enclosed organelle found in eukaryotic cells. It contains most of the cell's genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to formchromosomes. The genes within these chromosomes are the cell's nuclear genome. The function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell by regulating gene expression- the nucleus is therefore the control center of the cell. The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the entire organelle and separates its contents from the cellular cytoplasm, and the nuclear lamina, a meshwork within the nucleus that adds mechanical support, much like the cytoskeletonsupports the cell as a whole. Because the nuclear membrane is impermeable to most molecules, nuclear pores are required to allow movement of molecules across the envelope. These pores cross both of the membranes, providing a channel that allows free movement of small molecules and ions. The movement of larger molecules such as proteins is carefully controlled, and requires active transport regulated by carrier proteins. Nuclear transport is crucial to cell function, as movement through the pores is required for both gene expression and chromosomal maintenance.Although the interior of the nucleus does not contain any membrane-bound subcompartments, its contents are not uniform, and a number ofsubnuclear bodies exist, made up of unique proteins, RNA molecules, and particular parts of the chromosomes. The best known of these is thenucleolus, which is mainly involved in the assembly of ribosomes. After being produced in the nucleolus, ribosomes are exported to the cytoplasm where they translate mRNA.

Answer 2

The nucleus of a sperm cell, much like a regular cell, contains the chromosomes needed to support life. However, the sperm cell only contains one half, to be combined with an egg cell's half to create new life.

Answer 3

chromosomes and the transportation systems

Answer 4

The important structures that are found inside of nucleus of a sperm cell are chromosomes. Sperm cells have two different chromosomes, one X and one Y.

Answer 5

chromosomes.

Answer 6

animail cells and plant cells

Answer 7

chromosomes
